Axial Flow Ventilation Submersible Dirty Water Pump Single Stage With Motor Drive

Model description:

500ZDB-70J

500: Nominal water outlet caliberof pump (mm)

Z: Axial flow

DB: Electric pump

70: 1/10 of pump specific speed

J: New design, speed down.

Maintenance:

Measure the insulation resistance with megohm meter once a month and at least operate the pump for 30 minutes to prevent from rusting during shutdown.
It is recommended to check quick-wear parts (mechanical sealing, bearing) and exchange lubricating grease and lubricating oil in oil container after the accumulated operation time is up to 4000 hours.

Application:

1	The two models ZDB and HDB submersible electric pump can be used in irrigation and drainage of agricultural field
2	The two models ZDB and HDB can also be used in supply and sewerage water of factory, mine, dock, urban construction,
3	water supply works and power station.

Features:

1	Adopting this type of submersible electric pump is the most through approach for building pump station along the river and lake area where the water level fluctuate greatly, as well as fluctuate the problem of flood prevention of pump; moreover, the major shaft and intermediate shaft are not required any more,and the machine set can operate more steady and reliable.
2	Submersible electric pump has double and triple mechanical seal and F grand insulation (155oC thermostable ) with protection grand IP68 (IEC). The pump has hydraulic model of nationwide unified design, which has high reliability and has the same performance of the conventional hydraulic pump so that the customer can select the model easily.
3	As its operation submerged into water, the electric pump can greatly simplify geotechnical engineering and building structure engineering of pump station, reduce erection space and save 30%-40% construction cost.

Construction:

The rotor has three sets of bearings and two sets of mechanical seals.
The rotation direction of the submersible motor is counterclockwise viewed from the shaft-extension end.

Performance parameter: 350ZDB-50
